Never tried that particular one, but it has characteristics of others I have tried and rejected. One, it is limited in where it can be deployed, therefore, it only traps beetles in that one spot (inside a super). Before I changed all my bottom boards to screened bb's with oil traps underneath, I found the bees usually corraled most of the shb's into the corners of the bottom, not in the supers. I have watched as a bee really got after a shb it tumbled down the comb to the bottom--right to its' well-deserved death in the oil pan! :evil: If your hives are tight, the only way in is through the entrance, over the screen. Most don't survive the phalanx of guard bees to ever get to the supers. The ladies chase them through the screen where they get a crash-course in swimming!
